I hate those small 2.4 GHZ on top of my Transmitter, Specially all those Spektrum and JR Radio, cause the Spektrum and JR Transmitter have a very long Antenna, that I have difficulty storing on my Flight Box.

here is my solution, I just remove the Antenna and put it inside the Transmitter......you can easily convert it to its original looks, just incase you want to Sell it.

I have not performed a Ranges Test, But I guess, it would have the same performace.......my next plan is to use an 2.4 GHZ Spektrum Analyzer to measure its Signal Strength, while the Transmitter is about 500 to 1Km away. and make a signal Strenght Reading on Each Position:
1. Few Inch away from Transmitter Base
2. at the Transmitter Base
3. inside the transmitter

any way, range is not an issue for me, cause I only use it to fly my MCPX helicopter.
